I'm planning to head to Sacramento for the national Falcon convention this year, including the "Cruise Old Sacramento" event. I'm picturing slow speeds on a hot July day, and have been thinking about a high-flow thermostat, like a Robert Shaw or others to help with low speed cooling. Anybody have thoughts on that?

I'm currently running a stock water pump, Silla aluminum radiator, stock Ford-style fan shroud and a 180 degree 'stat, which puts my gauge at about 1/4 up here in (cooler) Oregon. Seems to work fine, although when I idle in traffic for a while, the idle seems to slow slightly and gets a little more ragged.

I'm looking to combat overheating at slow speeds wherever I drive.
